Sleep disturbances are common in patients admitted to the coronary care unit (CCU), where continuous light, noise, and monitoring equipment disrupt normal sleep. Poor sleep in CCU patients can worsen heart function and increase the risk of delirium.
This study tested whether wearing an eye-ear sleep band, a single, adjustable product that blocks both light and noise, could improve sleep quality in CCU patients compared to standard care alone.
One hundred adults admitted to the CCU with acute coronary syndrome were enrolled. Using a crossover design, each participant spent one night wearing the eye-ear sleep band and one night receiving standard CCU care, in a randomly assigned order. Sleep quality was measured each morning using a validated questionnaire (Richards-Campbell Sleep Questionnaire).
The eye-ear sleep band is a simple, low-cost, non-pharmacological tool that may help improve sleep in CCU patients.
